METHOD AND ARRANGEIEENT FOR THE ERECTION 0F DRY GASOMETERS.

Application nled December 26, 1923. Serial No. 682,842.

To all whom, it may concern:

Be it known that I, KONRAD JAGsoHrrz, a citizen of German of No. 27 Weintorstrasse, residing at ainz, Germany, have invented certain new and useful Improvements in a Method and Arrangement for the Erection of Dry Gasometers, of which the following is a specification.

The erection of dry gasometers having slidable discs to close the variable gas space takes place, as a rule, by suspending the previously constructed closing disc as a working stage or platform upon a mast or upon the wall posts of the gasometer so as to be slidable thereon and adjustable at any desired hei ht, in order to enable an exact fitting of t e plates forming the outer shell of the gasometer.

This known method admittedly ives the desired amount of accuracy in the tting of the plates, but it requires a special time consuming adjustment or alinement of the wall posts, the position of which has to be continuously measured and re-examined.

The object of this invention, therefore, is to eliminate this measuring work and to thus save time and labour, and it mainly consists in a method and an arrangement to positively and forcibly carr out the required alinement by means o the closing disc itself. In order to thereby avoid undue stresses in the wall posts and consequent distortions, such as are likely to occur when pulling the disc up the said wall posts; the disc is preferably raised by means of compressed air pressure from below in a manner which in itself is known.

In this way it is possible to obtain a permanent correct position of the disc itself as well as of the wall posts which are' positively alined by the disc during its upward travel, so that the fitting of the wall plates may be effected without having to continuously measure and re-examine the measurements, lwhereby time and labour ma be saved.

e means for carrying out the new method of wall post adjustment ma be chosen to suit each particular case. In a preferred form of the invention, however, s cial auxiliary frames are used, which c osely embrace the posts and which are temporarily fixed to such parts of the closing vdisc, or to the strengthening ring thereof,

which correspond to the positions of the guide rollers of the disc, or of the wall posts respectively. The said auxiliary frames are provided with auxiliary guide rollers kby means of which the individual posts are pressed against the guide rollers of the disc and thereby alined in position. The auxiliary rollers are contoured in the manner of stepped pulleys and they are arranged with their stepped surfaces bearing against the narrow sides and the reverse side of a flat rail which, for the purpose, is fixed to each of the wall posts.

The drawing illustrates an arrangement according to the invention by way of example.

Fig. 1 shows the auxiliary frame with part of the strengthening girder work of the closing plate and one of the wall posts in side elevation.

Fig. 2 is a plan view of Fig. l.

Fig. 3 is a vertical section of a gasometer equippedl with the invention and Fig. 4 is a fragmentary kplan view thereof.

In the drawin s1 denotes the guide roller of the closing isc.,I hereinafter called the main guide roller, which is carried by a jib-like frame 2 of the strengthening girder work 3 of the closing disc a. To this frame 2 is temporarily fitted an auxiliary frame 5 arranged to enclose the wall post 4 of the gasometer and carrying a pair of auxiliary guide rollers 6 which are contoured in the manner of stepped pulleys and of which the stepped surfaces are adapted to press against a flat rail 7 fixed to the wallpost 4 in such a manner, that this rail, and therewith the said wall post, are pressed against the main guide roller 1 and thus effectively secured against lateral displacement. An undesired displacement of the jib-frame 5 may be revented by the provision of ties 8.

t wi be seen rfrom the drawing that on the closing disc being raised from below, for example by means of compressed air, the said rollers 1 and 6 press against the rail 7 at all of its four sides thus causing ometers having closing discs, which serve, in each case as a working stage during` erection, said method consisting in raising the disc from below as by means of compressed air along the wall posts ofthe gas' ometer and operating thereby a means whereby the said wall posts by the movement of the disc itself are simultaneously aligned.

3. An arrangement for the alinement, during the erection of dry gasometers, of the wall posts thereof comprising in combination with the closing disc of the gasometer and the main guide rollers thereof, of auxiliary frames adapted to enclose each of the wall posts, and means on the` auxiliary frames to press the said wall posts into close contact with the main guide roller during the upward travel of the closing disc.

4. An arrangement for the alinement, during the erection of dry gasometers, of the wall posts thereof, comprising in combination with the closing disc and the main guide rollers thereof, of temporarily fixed auxiliary frames enclosing the said wall posts, auxiliary guide rollers in the said frames to ress the wall posts into close contact with) the main guide rollers during the ulpward travel of the closing disc.

5. n arrangement Vfor the alinement, during the erection of dry gasometers, of the wall posts thereof comprising in combination with the closing disc and the main guide rollers thereof, of auxiliary frames temporarily fixed to the strengthening rin of the closing'dise and each enclosing wal post, auxiliary guide rollers in the said frames to press the wall posts into close contact with the main guide rollers during the upward travel of the closing disc.

6. An arrangement for the alinement, during the erection of dry gasometers, of

the wall posts thereof comprising in combination with the closing disc 'and the main guide rollers thereof, of a flat rail in fixed connection with each of the wall posts, auxiliaryframes temporarily fixed to the closing disc, each frame enclosing a wall post and the flat rail connected therewith, auxiliary guide rollers in the said frames of stepped pulley formation pressing against the opposite edges and the outer surfaces of the flat rails so as to keep the said rails in close contact with the main rollers during the upward travel of the closing disc.

In testimony whereof I ah'ix my signature in presence of two witnesses.
